Description
Technical field
The present invention relates to boiler water processing technical field, relate in particular to a kind of nano titanium oxide boiler scale-inhibition descaling water disposal facility.
Background technology
Water as thermodynamic medium since, the fouling of heating surface and heat-transfer surface just becomes a difficult problem of heat exchange process.Boiler is most widely used Thermal Equipment, and Industrial Boiler generally refers to except thermal power generation, the boiler using in people produce and live.Up to the present nearly more than 50 ten thousand of all kinds of in-service Industrial Boilers of China according to incompletely statistics, approximately 1,800,000 steam ton/hour, the fire coal of take is 85% left and right that main boiler accounts for sum.Experimental data shows, generally, when 0.5 millimeter of boiler scale, will consume 2% fuel more; While being 1 millimeter, fuel consumes 10% more; While being 3 millimeters, fuel consumes 25% more.
With fouling 1mm, fuel consumption increases in 10%, coal-fired consume more; 5737.5 ten thousand tons/year, coal-fired in 500 yuan/ton, financial loss; 28687500000 yuan/year.
Gyp meeting causes huge financial loss, also jeopardizes the safety of boiler, shortens the work-ing life of boiler; Will there is following harm in gyp:
One, the thermal conductivity that reduces boiler, when scale forming is larger, the cooling of boiler tube also can be affected, and furnace wall temperature is obviously raise, and then cause drum, that tube wall occurs is overheated, distortion, crackle, bulge, booster are even exploded etc.
Two, waste of fuel, the thermal conductivity of incrustation scale is low, and the thermo-efficiency of boiler surface and heat-transfer surface is reduced, and in the situation that exerting oneself on an equal basis, consume fuel increases.
Three, affect water cycle, the water wall tube fouling of boiler, flow area will diminish, and increase the resistance to flow of water in boiler, possibility blocking pipe when serious, the water circulation system of destruction boiler, the probability that causes security incident also obviously increases.
Four, shorten the work-ing life of boiler, gyp produces underdeposit corrosion, is the one of the main reasons that boiler is scrapped.
Five, scale removal harm, gyp is inevitable, and scale removal is the maintaining method that guarantees the normal operation of boiler, and scale removal improper measures will cause the damage of boiler inner wall, is also one of reason that shortens boiler work-ing life.
The object of boiler water processing is to stop fouling, existing two kinds of forms, and boiler is outer to be processed and the interior processing of boiler.
1, boiler is processed outward; With Na-ion exchanger, calcium, magnesium ion are swapped out to water body, be that water softening is processed, 1 ton of soft water of every production approximately need to consume 2 kilograms of salt, salt enters with Na-ion exchanger regeneration waste liquid the permanent pollution that water body can cause water body, and developed country has carried out restriction or forbidden the use of Na-ion exchanger.
2, in boiler, process; In boiler, add Scale inhibitors, make into dirty material and in boiler, do not form hard scale, form grain slag, easily clean.Phosphorus is that Scale inhibitors is to use more a kind of Scale inhibitors, and phosphorus enters water body and forms eutrophication, raw algae hereby, and contaminate environment, developed country strictly carries out limit phosphorus and the measure of taboo phosphorus.
Publication number is CN 201547960U, the Chinese patent literature that open day is on August 11st, 2010 discloses a kind of scale inhibition device for vertical water boiler, it is characterized in that: a scale inhibition plate is set up on the top, inner bag top at vertical type water heater boiler, the strong heat transfer zone in inner bag top and smoke pipe bottom that incrustation scale directly scorches from flame produces, assembly is transferred to scale inhibition plate and deposited.
The disclosed scale inhibition device for vertical water boiler of this patent documentation, by setting up scale inhibition plate on top, inner bag top, the incrustation scale originally producing on inner bag top and smoke pipe bottom is shifted, incrustation scale finally still can deposit in boiler, can not fundamentally stop the generation of incrustation scale in boiler.
